A wind energy system transforms the kinetic energy of the wind into mechanical or electrical energy that can be harnessed for practical use. Wind energy technology is developing fast, turbines are becoming cheaper and more powerful, bringing the cost of renewably-generated electricity down. There are two types of wind machines used today: horizontal–axis and vertical-axis. Most windmills are the horizontal-axis type. One wind machine can produce 1.5 to 4.0 million kilo-watt-hours (kWh) of electricity a year. That is enough electricity to power 150-400 homes. The U.S. Department of Energy estimates that by 2020, wind energy will offset approximately 4.5 percent of the carbon dioxide that would otherwise be emitted by other electricity sources. In 2005, electricity generation accounted for 39 percent of the nation's total CO2 emissions.
Stalix’s technology is in micro-windmill. This is a new technology that uses a large number of micro-windmills to generate electricity. The micro-windmills are built around custom permanent magnet alternators, and custom injection molded plastic blades.
